Would it be lowering pressure, upping the pressure, lowering pressure support, or lowering pressure support if anything at all? Many of my nights consist of frequent arousals and may have found the culprit, but I could be wrong. I noticed looking back on historical data, that lower pressures had less UF#2 identified, but this could be a coincidence, I'm not sure.
Attached is last nights data from OSCAR:
16.0/12.0 PS4.0 (Been using these settings for 65 days now consistently)
